The suppression of contractions is often only partial and tocolytics can only be relied on to delay birth for a matter of days. Depending on the tocolytic used, the pregnant woman or fetus may require monitoring (e.g., blood pressure monitoring when nifedipine is used as it reduces blood pressure; cardiotocography to assess fetal well-being ...
Montevideo units can be more simply calculated by summing the individual contraction intensities in a ten-minute period, a process which should arrive at a result identical to the original method of calculation. [2] Generally, above 200 MVUs is considered necessary for adequate labor during the active phase.
Frequency: the number of contractions per unit time. Duration: the amount of time from the start of a contraction to the end of the same contraction. Resting tone: a measure of how relaxed the uterus is between contractions. With external monitoring, this necessitates the use of palpation to determine relative strength.
In small doses (1–4 mg/day), PGF 2α acts to stimulate uterine muscle contractions, which aids in the birth process. However, during the first trimester and in higher concentrations (40 mg/day), [9] PGF 2α can cause an abortion by degrading the corpus luteum, which normally acts to maintain pregnancy via the production of progesterone. Since ...
A nonstress test (NST) is a screening test used in pregnancy to assess fetal status by means of the fetal heart rate and its responsiveness. A cardiotocograph is used to monitor the fetal heart rate and presence or absence of uterine contractions. The test is typically termed "reactive" (also "reassuring") or "nonreactive" (also "nonreassuring ...
Yahoo Life asked doctors to weigh in on natural ways for pregnant women to start labor and whether they're fact or myth. Can you induce labor at home? 7 common myths about kick-starting labor, and ...
Uterotonics are used both to induce labor and to reduce postpartum hemorrhage. [1] Labor induction in the third trimester of pregnancy may be required due to medical necessity, or may be desired for social reasons. Generally, labor induction is indicated when the risk of carrying the pregnancy outweighs the risk of delivering. These reason ...
While blue cohosh can be used to induce labor, “it carries potentially serious though rare risks to mother and baby,” said Dr. Aviva Romm, a midwife and licensed physician, who wouldn’t ...
